'Fantasy Island is a resort, where there is very little that the host,
Mr. Roarke cannot provide. Thus we have visitors who have adventures and
fantasies that should be impossible, but this island can accommodate them,
such as visits to any time period they want, meet absolutely anyone they
see to do something they request such as getting William Shakespeare to
write a play for them. The only constant (until the final season) was at
the sight of the incoming visitors, that Mr. Roarke's midget assistant
runs up to the bell tower to ring the bell and shout
"De plane!, De plane!" (Internet Movie Database)
